Windows Security, the antivirus program built into Microsoft’s operating system, is generally sufficient for most users. It provides a decent level of protection against various threats, but a few important features, like Memory Integrity, remain turned off by default. This setting is crucial as it protects your system’s memory from malicious software that attempts to exploit Windows drivers, potentially taking control of your PC.

When you enable Memory Integrity, it activates Virtualization Based Security (VBS). This feature separates the code verification process from the operating system, creating a secure environment and adding an additional layer of protection. Essentially, VBS ensures that any code executed on your system is thoroughly checked, preventing malicious programs from sneaking through Windows’ defenses.

However, Microsoft disables Memory Integrity by default to maintain smoother app performance. Some applications may not function properly with this feature on, as the extra layer of security can interfere with the way certain programs execute code. For users who prioritize app performance over security, this trade-off may seem appealing.

But for those concerned about malicious attacks, enabling Memory Integrity is a smart choice. It prevents malware from bypassing the usual system checks, providing peace of mind when dealing with potential security threats. On older PCs, though, you might notice a slight reduction in performance once Memory Integrity is activated.

Curious to see how your system handles this extra protection? Enabling and disabling Memory Integrity is a simple process. First, type “Windows Security” into the search bar or Start menu. Under Device Security, you may see a notification if Memory Integrity is off. Click Core Isolation, then toggle Memory Integrity on. To deactivate it, return to the same settings and flip the switch off.

It’s not just Memory Integrity that comes disabled by default in Windows. Microsoft leaves certain protections off to strike a balance between security and user experience. Another useful feature you can enable is ransomware protection, which safeguards specific folders and prevents unauthorized apps from locking you out of your data. Similarly, you can turn on advanced app screening to block potentially harmful programs.

While leaving Memory Integrity and other protections off can offer a smoother computing experience, activating them significantly strengthens your system’s defenses against cyber threats. It’s a choice between performance and security, but for those prioritizing protection, flipping these settings on is an easy step towards a safer PC.
